Compare any two graphics cards:
GeForce 8800 GT 1GB vs GeForce 8800 GT 512MB
IntroThe GeForce 8800 GT 1GB has a clock frequency of 600 MHz and a GDDR3 memory speed of 900 MHz. It also features a 256-bit bus, and makes use of a 65 nm design. It features 112 SPUs, 56 TAUs, and 16 Raster Operation Units.Compare those specifications to the GeForce 8800 GT 512MB, which comes with a clock speed of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit bus, and makes use of a 65 nm design. It is comprised of 112 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthBoth cards have the exact same memory bandwidth, so theoretically they should perform the same. (explain)
Texel RateBoth cards have exactly the same texel rate, so in theory they should perform equally good at at AF. (explain)Pixel RateBoth cards have the exact same pixel rate, so in theory they should be equally good at at AA, and be capable of handling the same resolutions. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
